Application filed November 21, 1902. Serial No. 132,227 (No model.)

To all whom it may concern..-

Be it known that LPHILIP SOMMER,a citizen of the United States, residingat Chicago, in

the county of Cook and State of Illinois, have 5 invented certain newand useful Improvements in Slicing-Machines, of which the following is aspecification, reference being had to the accompanying drawings.

' This invention relates to slicing-machines designed,primarily,forslicingloaves of bread,

and has for its object the production of a machine for the purposespecified that will be simple in construction, that will cut slices ofuniform width from the loaf, and that will immediately after cutting offa slice push such slice away from the knife and the rotating gage thatturns with the knife, pushing also along the base-board on which thebread rests such other slices as may have been just previously cut, sothat when all the slices desired have been cut from the loaf they willlie closely together in an even compact mass that can be readilyhandled. I attain this object by the devices and combinations of devicesshown in the drawings and heroinafter fully described.

That which I regard as new will be set forth in the claims.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is a rearelevation; and Fig. 3 is a side elevation, partly broken away. Referringto said drawings, a indicates a base which may, if desired, be providedwith a vertical side piece I) to form a guide for the loaf beingoperated upon, the base a being of a width to accommodate a loaf ofbread of ordinary size.

0 indicates a support secured in the construction shown to the verticalside piece 6. d'indicates a shaft supported in a suitable bearing e,formed with or secured to the support 0, such shaft extendinglongitudinally of and over the base ct and carrying at one end a disk orplate f, which may, if desired, be cast integral withthe shaft (1. Asshown,

this disk or plate f has a notch g of considerable size, from one sideof which notch projects an extension h, the outer edge of which forms acontinuation of the curved edge of said disk or plate f, which extensionis, as shown, also curved outward, so as to project beyond the plane ofthe forward face of the disk or plate.

11 indicates a curved cutting-knife secured in the construction shown atone end to the forward end of the shaft d and separated from the disk orplate f by a suitable washer, such separation corresponding to thethickness that it is desired to have the slices of bread.

j indicates a transverse groove in the face of the base a to receive theedge of the knife, so as to insure the complete separation of slicesfrom a loaf.

indicates a narrow groove in the projecting end of the extension 71.,into which the outer end of the knife '5 is inserted. By thisconstruction I provide means for rigidly holding the knife at both itsends and am consequently enabled to use a very thin blade for the knifewithout danger of its bending or breaking, which would be apt to occurin some cases if a very thin blade were employed that was unsupported atits outer end.

Zindicates a beveled gear secured to one end of the shaft (Z. mindicates another beveled gear secured to a shaft n, mounted in asuitable bearing 0 and meshing with the firstnamed gear, so that uponthe rotation of the gear on the shaft d and the plate or disk f andknife t, carried thereby, will be rotated.

p indicates a crank formed on the end of the shaft 11, by means of whichthe gear m secured on such shaft can be rotated.

In operation a loaf of bread placed on the base a forward of the disk orplate f and knife t'is to be moved by hand againstsaid disk or plate,while at the same time the 'movable parts of the machine are operated.The knife, coming in contact with the loaf, will out off a slice, andthe extension h'following in between such slice and the body of the loaffrom which it was cut will by reason ofits curvature away from the planeof the outer face of the disk or plate act to force such slice in rearof such disk or plate. The

loaf of bread being continually pushed forward by hand against such diskor plate, other slices will be similarly cut off and in the same mannerpushed behind the disk or plate, the rearward motion of each sliceacting to push back the previously-cut slices,

so that when the desired number of slices have been out such slices willbe found evenly and compactly arranged on the base a, so as to be easilyremoved therefrom. It is evident that the disk or plate facts as a gageby which the thickness of the slices is regulated and that the slicesmust be uniform as regards thickness.

That which I claim as my invention, and desire to secure by LettersPatent, is-

1. The combination with ashaft, and means for supporting and rotatingthe same, of a plate or disk carried thereby and having a notch therein,a curved and forwardly-inclined projection extending from one edge ofsaid notch, and a rotatable knife mounted on said shaft and locatedforward of said disk or plate in substantially the same vertical planeas the forward end of said projection and connected at its outer endwith said projec tion, substantially as specified.

2. The combination with a shaft, and means for supporting and rotatingthe same, of a plate or disk carried thereby and having a notch therein,a curved and forwardly-inclined projection extending from one edge ofsaid notch and having a groove in its forward edge, and a knife alsocarried by said shaft so as to rotate therewith, located in front of andaway from said disk or plate, and having its outer end inserted in thegroove in the end of said projection, substantially as specified.

3. The combination with a shaft, and means for supporting and rotatingthe same, of a plate or disk carried thereby, a forwardly-inclinedprojection extending from said plate or disk, and a rotatable knifemounted on said shaft and located forward of said disk or plate insubstantially the same vertical plane as the forward end of saidprojection,

substantially as specified.
